Crotonic acid Chemical Properties,Uses,Production
Chemical Properties
Crotonic acid is a white or colorless, crystalline solid with a pungent odor. May be transported as a molten liquid.
Uses
Crotonic acid is used in the synthesis of resins, polymers, plasticizers, and drugs. It is also used as a softening agent for synthetic rubber and in medicinal chemicals.
Definition
Exists in cis and trans isomeric forms, the latter being the stable isomer used commercially. The cis form melts at 15C and is sometimes called isocrotonic acid.
General Description
A white crystalline solid. Shipped as either a solid or liquid. Melting point 59°F. Soluble in water and less dense than water. Flash point 190°F. Corrosive to metals and tissue.
Air & Water Reactions
Soluble in water.
Hazard
Strong irritant to tissue.
Health Hazard
TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Fire Hazard
Combustible material: may burn but does not ignite readily. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.
Safety Profile
Poison by intraperitoneal route. Moderately toxic by ingestion, skin contact, and subcutaneous routes. A powerful corrosive and irritant. Flammable when exposed to heat or flame; can react with oxidizing materials. To fight fire, use alcohol foam, CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes.
Potential Exposure
Used to make plastics, resins, plasticizers, lacquers, and medicines; other chemicals as a chemical intermediate.
Shipping
UN2823 Crotonic acid, solid, Hazard class: 8; Labels: 8-Corrosive material.
Incompatibilities
May form explosive mixture with air. A strong reducing agent. The aqueous solution is a weak acid. Violent reaction with oxidizers, combustibles, strong bases; peroxides. Moisture or strong sunlight (UV) may cause explosive polymerization. May accumulate static electrical charges, and may cause ignition of its vapors. Combustible when exposed to heat or flame. Compounds of the carboxyl group react with all bases, both inorganic and organic (i.e., amines) releasing substantial heat, water, and a salt that may be harmful. Incompatible with arsenic compounds 938 Crotonic Acid (releases hydrogen cyanide gas), diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, sulfides (releasing heat, toxic, and possibly flammable gases), thiosulfates, and dithionites (releasing hydrogen sulfate and oxides of sulfur).
